Throughout the nineteenth century, the Ottoman Empire grew weaker and seemed headed for collapse. It became the object of the ambitions and rivalries of the European powers. Under its suzerainty, Syria, including the Mount Lebanon region, was a key area strategically since it dominated the access routes to India and southern and eastern Asia. France and England both tried to impose their influence by way of local communities. France acted through the Christian Maronites, while Britain used the Druzes. In the spring of 1860, trouble broke out between the two communities, resulting in the massacre of thousands of Christians. The European powers, at the behest of the government of Napoleon III, agreed to intervene by sending a commission of inquiry and troops. The expedition’s official mission was to help the Ottoman Empire to restore order and to protect Christians.
This thesis shows that imperial France pursued political and economic goals with regard to Syria and Lebanon. The historiography had not previously analyzed in depth the real French mobile in this expedition. The political and economic ambitions were far more important in its decision to set in motion an expedition than the "humanitarian" Christian duty of providing protection or the satisfaction of the public opinion. Far from being deterred by the catastrophe of the massacre that threatened the survival of its protégés and therefore its influence in Syria, Paris, and especially its foreign minister E. Thouvenel, managed to turn the situation to his advantage. Skilfully using the desire of interference of other powers and its role as protector of Christians, France managed to corner England, which opposed the intervention, and justify it on principles far removed from its real objectives. The troubles finally represented for her an opportunity to widen the autonomy of the Mountain vis-à-vis the central authority of the Ottoman Empire and to increase the economic and political power of its clients through the revision of the administrative status of the region. In so doing, it has strengthened its influence in the eastern Mediterranean and moved a step closer to dominating Syria.
